Chicks outside with a lamp? with 45F lows?

[Chickies2020]

The overnight lows are about 45F - I moved the brooder outdoors. It has 4 walls and a tarp loosely over wire on the top (there is ventilation). I have a Binsea EcoGlow in there - there are 3 x 5 week old chicks and 2 x 3 week old chicks. Think they will be ok or should I move them in? (I'd really rather not but dont want them to freeze).

I've got 5, 4 week Olds and 5, 1 week Olds all outside. The 1 week Olds have been outside since day 2. I've got them all inside my coop with plywood walls but there is ventilation and a couple small windows. It's gotten down to 38 a couple nights. Mine have all done well. Just keep the lamp low enough to maintain a good temp around sunrise. I bought a wireless thermometer for $10 at Walmart. I can keep an eye on it while still inside and adjust the lamp accordingly.

With just a tarp over the top, keep in mind about predators

There's sturdy wire on top with the tarp on top of that to help keep the breeze out.
